Big Rig Crashes Into Funeral Home Causing Fire In San Francisco

The driver and a passenger in the big-rig, that was delivering food to nearby Starbucks, were transported to San Francisco General Hospital for minor injuries, according to police.

A caretaker inside the funeral home escaped unharmed.

It was unknown why the driver lost control of truck crossing over concrete-center medium, possibly rupturing the fuel tanks, and slammed into the funeral home before exploding into flames that reached 20 feet, according to Fire Battalion Chief Kevin Taylor.

“We’re fortunate that very little fire extended inside the building,” Taylor said pointing out the entry point was made of stucco.

Further inside, the structure was made of wood.

“If the vehicle had landed 20 more feet further than what it did, we would have had a much more intense fire going,” Taylor told KCBS.

Jerry Lynn Sullivan, wife of the building’s owner said she was thankful that no one was killed.

“It could have been a lot worse all the way around,” she said.

Westbound Market at Sanchez Street will be closed until until cleanup crews can 150 gallons of remaining fuel from the tanks and tow the burned what’s left of the rig.

In the meantime, Muni placed a shuttle bus on the F-Market line for the duration of the cleanup.
